针对煤矿井下有线监控系统存在布线困难、监控盲点、灵活性能差等问题,设计了一种基于Zigbee无线通信技术的煤矿井下人员监控无线接收分站。该无线接收分站将有线通信与无线信号传输相结合,克服有线系统可扩展性,布线、维护等方面的缺点,又避免全无线网络信号传输过程中的网络延时,减少数据丢失,并且很大程度上降低噪声对信号的影响。重大事故发生时,提供营救人员重要信息,为快速救灾提供便利,具有较高的实用价值。 Aiming at the problems of difficult wiring, blind spot monitoring and poor flexibility in coal mine cable monitoring system, a wireless monitoring sub-station for coal mine personnel monitoring based on Zigbee wireless communication technology was designed. The wireless receiving substation combines wired communication and wireless signal transmission to overcome the disadvantages of the scalability, cabling and maintenance of the wired system and to avoid the network delay in the whole wireless network signal transmission process and reduce the data loss To a large extent reduce the impact of noise on the signal. In the event of a major accident, it provides important information for rescue workers and facilitates rapid disaster relief with high practical value.
